AMD 2800+ shows as AMD2200+

sounds like you need to go into your bios and set the FSB to 166mhz (166*2 = 332) near enough to the 333mhz fsb of the processor (dont forget you would need PC2700 ram), dont know your particular board but most motherboards have a setting for CPU fsb.

have a look round but dont go changing things you shouldnt. tread lightly.
